Abstract

L'invention porte sur des machines de décapage de sols, qui comprennent des caractéristiques de fonctionnement et/ou d'entretien améliorées. Une machine de décapage de sol selon la présente invention peut être entraînée et dirigée sous la commande d'un actionneur linéaire commandant le fonctionnement d'une paire de moteurs hydrauliques associés à une paire de roues motrices. La machine de décapage de sol peut être alimentée par batterie, mais comprend des composants électriques (par exemple, un moteur primaire) fonctionnant sous une alimentation à courant alternatif (CA), améliorant la durée de vie de la batterie. Les différents composants de la machine de décapage de sol peuvent être localisés et conçus (par exemple dans des modules) pour un accès facile et un remplacement simplifié (par exemple par utilisateur). La localisation d'un siège sur la machine de décapage de sol peut être adaptée de façon à permettre à un utilisateur de n'importe quel poids de conduire la machine de décapage de sol sans interférer avec une répartition de poids de la machine de décapage de sol.
